Iszard and wilks used a differential technique to study the surface coating on cellophane . 伊斯扎德和威耳克斯应用差示技术,研究粘胶薄膜的涂层。
The paper conducts partition and comparison of pollution load within the basin during 1991 ~ 1999 period by taking shaanxi section of weihe river basin as an example and using separation method of hydrograph and rainfall differential technique respectively 以渭河流域陕西段为实例,分别运用径流分割法、降雨量差值法对流域内1991 ~ 1999年污染负荷进行了分割,并进行相互比较。
We made use of wheatstone bridge to control ratio of heating power between the samples , thus , it enable to control and measure the differential heating power accurately . consequently , it improves sensitivity of the system . the resolution of the measurement can reach from 1 : 1000 to 1 : 10000 or better in comparison with the traditional differential technique 我们测量了聚苯胺及其掺杂盐酸后在1 . 8k至45k的热容,利用声子分形子模型来处理非晶态对比热的贡献,对获得的数据进行处理,发现eb和es的比热数据均不符合德拜理论,超出德拜模型的比热来源于非晶态的贡献。
